Monetary Policy: Central Bank Tools
Short: Central banks use various tools to control the money supply and interest rates in an economy to promote price stability and economic growth. The key tools are the key interest rate, reserve requirements, and open market operations.
In more detail: Changes in monetary policy usually only affect the overall economy after a delay of several months.
In detail
- Key interest rate: The rate at which banks can borrow money from the central bank indirectly influences all other interest rates in the economy.
- Open market operations: By buying and selling government bonds, the central bank directly controls the amount of money in circulation.
- Reserve requirements: Banks must hold a certain percentage of their deposits at the central bank, which influences the available amount of credit.
- Quantitative easing: In times of crisis, the central bank buys securities on a large scale to pump additional money into the economy.
- Rate cuts during a downturn: Lower rates make credit cheaper and are meant to stimulate investment and consumption.
- Rate hikes against inflation: Higher rates make credit more expensive and are meant to curb excessive demand and rising prices.
- Central bank independence: Many central banks operate independently of the government to protect monetary policy decisions from short-term political pressure (konjunkturzyklus-grundlagen, inflation-grundlagen).
